watchdog: constify watchdog_ops and watchdog_info structures

These watchdog_ops and watchdog_info structures are only stored
in the ops and info fields of a watchdog_device structure,
respectively, which are const.  Thus make the watchdog_ops and
watchdog_info structures const as well.

Done with the help of Coccinelle.  The rules for the watchdog_ops case are
as follows:

// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct watchdog_ops i@p = { ... };

@ok@
identifier r.i;
struct watchdog_device e;
position p;
@@
e.ops = &i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct watchdog_ops e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct watchdog_ops i = { ... };
// </smpl>
